Abstract

Mobile phones are backbone of the mobile communications and have experienced fastest growing segment in the consumer market. In the 3G and 4G mobiles, video recording is an essential entertainment features so the user can record and play the video within the mobile phone. In this paper, video capture and playback implementation had been carried out by integrating the camera module to the GSM phone. An alaysis of the video processing had been carried out. Image sensor and LCD module had been interfaced with the base band processor through the video processor. To interface the different module necessary PCB schematic diagram had been arrived. Software implementation had been carried out for the Human Machine Interface for various settings of the camera module, which is integrated with the video processor. The developed playback system had been tested for the various senerious. In this video has been captured through the camera sensor and at the time of playback measured the resolution, power consumption and image transfer rates of the various modules used in the developed camera phone.

Abstract

In contrast with low end microprocessor, ARM9 core is quite a sophisticated processor. The Evaluation kit plays an important role in the prototype development and verification of the system design before taking to its actual system development hence it’s provide better confidence to the designer. In this paper a project for the Evaluation kit has been designed for embedded system engineer to implement and confirm the functionality of their operating systems which could lead to a comfortable deployment. The independent modules for the interfaces of the ARM9 processor have been designed and the schematics have been developed using OrCAD. From the tested schematics designed in OrCAD, the related PCB is designed using CADSTAR. An eight-layer board is designed for its signal integrity and complexity of the schematic designed. The designed PCB layer is then calibrated and Gerber files are then made and passed on the PCB board manufacturer for PCB fabrication. The PCB board made is then tested for interconnection continuity using multi-meter as the components are loaded on to the board.
